`FLOUR-BOLT.

SPECIFICATION forming part of Letters Patent No. 251,954, dated January3, 1882,

Application filed July 30, 1881. (No model.)

I To all uhom 'it may concern: I

Be it known that I, CHARLES SCHACHT, ot' Marine, in the county ofMadison and State of Illinois, havein vented a certain new and usefulImprovement in Flour-Bolts, reference being had to the accompanyingdrawings, forming a part hereof.

My invention relates to revolving bolts, and its object is to providemeans for keeping the bolting-cloth free from all obstructing materialand to prevent the flour from caking upon the cloth.

It is a well-known fact that the friction produced with the reduction ofgrain between the burrs brings the flour to a temperature at which itwill readily cake and will have a tendency to clog the meshes of thebolting-cloth, and this tendency of caking is increased with. the highergrades of llour.

My invention consists of looped fringes of cord, cloth strips, orleather straps pending from rods or stretched ropes or cables that areplaced parallel with the bolting-reel into the bolt-chest, and in suchrelation to said boilingreel that these fringes will drag upon andagainst the bolt, and that as the latter revolves these fringeswillsweep over and strike against the bolting-cloth, thereby preventingthe iiour from caking against and clogging the boltingcloth, as morefully `hereinafter described.

In the accompanying drawings, Figure l represents a cross-section of thebolting-chest and flour-bolt having my improvement. Fig. 2 is aperspective view of the same with one side and the top of thebolting-chest removed. Fig. 3 is an elevation of one arrangement of thelooped fringes of cord or other flexible strips as attached to theirsuspending rod or cable, and Fig. 4 is an elevation of anotherarrangement of the same.

The same letters designatethe same or correspondin g parts in all thefigures.

A denotes the bolting-chest, and B the hexagon or Octagon bolting-reel,all ot' which maybe constructed and arranged in any usual manner.

C D are two metal or wooden rods or cables, one along the rear and theother one above the bolt. These rods or cables are to extend the entirelength of the bolting-chest, and are se cured to the end walls by anywell-known means, or may be made to project thron gh the end boards, soas to beheld rigidly in position. To each of these rods is secured aseries ot'loops, a and b, made of cord, of strips of cloth, or ot"straps of leather, or ol' any other material that is flexible and issuitable in other respects. These loops may be single, or may be two ormore, one inside the other, and every one or every set may be attachedto the roIl or cable so as to adjoin the next one or the next set, asshown in Fig. 3; or these loops may be suspended in a manner to overlapeach other, as shown in Fig. 4, and only one rod or cablewith flexibleloops may be used instead ot' two, as shown in Figs. 1 and 2, all ofwhich will depend upon the kind andnature of the ilour to be bolted. Forthe purpose of adj usting the loops as to their length and their extentot contact with the bolting-reel, I can provide the rods G and D, eachon the end that projects through the end wall of the bolting-chest, witha ratchetwheel, so that it can be rotated to wind up a portion of or theentire iloops, and hold them in the desired position by locking thelratchetwheel with pawl pivoted to the boltingchest; or I can arrange therods or cables so that they will move in slots in the end walls ot thebolting-chest, so that they may be moved and adjusted vertically. Withthe rotation of the bolt-reel the exible loops will sweep over thebolting-cloth, and by passing each corner of thereel these loopswillstrike a light blow upon the bolting-cloth,that is sufficient toknock oft' any caking tlour or other obstructions, and thus will keepthe meshes clean and open or with the new process of reduction theirregularlyshaped middlin gs, which are apt to stick in the meshes, willbe repulsed into the flour-bolt by the sweeping and striking action ofthe loops. These flexible loops have the advantage over brushes oreXible aps that they will not obstruct the circulation ofthe atmospherethrough thebolts, which is ot' greatimportance for cooling the tlour, asotherwise the caking of the iiour will take place Inore readily; andanother advantage is that these loops will not damage the bolting-cloth,as is the yexperience with the use of brushes for a like purpose.

Another advantage secured by the use of the loops herein described overthose bolts where a ap or flaps is or are used is that the loops onlystrike against a small portion 0f the bolt-cloth .at one time, but yettouch itover all parts as the reel turns, and thereby clean the entiresurface thoroughly. The circulation of air brought about by the rotationof the reel is not obstructed by the loops, as it would be to a certainextent by a flap. A piece ot' cloth can be better cleaned from dustadheringthereto by striking it With a stick or a. rope at differentplaces than would be the case were one cloth to be struck With anotherover its WholeA surface atonce, or even if such cloth were struck by aboard over its entire surface at one time. By the means of the hereindescribed devices a higher grade of flour is obtained, the

bolting-cloth vwillA be more durable, and the bolts will perform moreWork.

What I claim as my invention is- The combination, with a reelbolt, ofone or more rods suspended Within the boltiug-chest and a series oflexible loops suspended from said rod or rods7 to adapt them on therotation of the reel-bolt to drag upon or against the boltiug-cloth,substantially as and for the purpose described.

In testimony whereof I have signed this specification, in-the presenceoftwo Witnesses, this 22d day of July, 1881.

CHARLES SCHAOHT.
